Research on bolt pre-tightening and relaxation mechanism under ...
2014年12月1日 · However, in a later experimental research, Junker 8 found that the bolts are more prone to loosening when subjected to dynamic loads perpendicular to the axial direction (transverse loads). And in this paper, some more detailed work is done to study the relaxation mechanism under transverse loads.
Pretightening sequence planning of anchor bolts based on …
2019年1月1日 · In this article, the pretightening sequence planning of anchor bolts based on structure uniform deformation for large CNC machine tools has been developed. During the pretightening process of anchor bolts, the accuracy datum of machine bed and the sufficient bolt joint stiffness should be ensured simultaneously.
